About Fuel & Water Separators / Polishers

Fuel & Water Separator Assemblies

Fuel water separators from Defender Marine are available for large bore diesel to outboard motors. Confirm your application to narrow down the search for the best boat water separator filter system. Fuel filter for inboard, stern drive, and outboard 2 and 4 cycle gas motors as well as separators that filter up to 120 Gallons of diesel per hour. In-line filters, clear bowl filters, and the new Racor SNAPP assembly could be the easiest way to access and maintain your gasoline engine fuel separation.

Fuel Polishers

From fuel/water separator filters to complete fuel transfer systems, Defender has your diesel fuel polishing system needs covered. Marine diesel fuel is notorious for contaminants and sitting to the dock only makes fuel polishing more of a necessity as the fuel tank is a popular spot for condensation and bacterial growth. Self-cleaning fuel polishing system kits, portable tank cleaners, and separator cartridges can also filter out hydraulic fluids, oils, and antifreeze.
